We would be more than happy to assist you in setting up an EMA environment to manage your vPro systems. Might I suggest that you open a support case https://supporttickets.intel.com so we can get some specific contact details and have a Technical Solutions Specialist reach out to you? There are many design decisions to consider, so a video/phone call may be a helpful way to get you started with your EMA installation.
A couple of documents you may want to consider looking at in the meantime are...
EMA Quick Start Guide
EMA Installation Guide (considering the size of your deployment you will want a distributed installation not a single server)
